If the belt being removed is to be reinstalled, mark the direction of its movement first so that it can be reinstalled in the same manner.
2. To remove the drive belt, remove the top engine cover (see Section 19 of Chapter 1) and loosen the belt tension by turning the tensioner in the direction of the arrow (see illustration 4.68) with a T60 Torx head. Remove the belt and release the tensioner. Installation is carried out in reverse order. Make sure the belt is positioned correctly in the grooves. If using a used belt, install it with the same side up (according to the marks made during removal).
3. To remove the drive belt tensioner, remove the belt from the tension roller (see paragraph 2) and unscrew the bolts (see illustration).
6.3. Tensioner mounting bolts.
Installation is carried out in reverse order.
4. To remove the drive belt idler roller, remove the belt from the tension roller (see paragraph 2) and unscrew the bolts (see illustration).
6.4. Intermediate roller mounting bolts.
Installation is carried out in reverse order.
5. To remove the crankshaft pulley, remove the drive belt (see paragraph 2), mark the position of the pulley and remove the 8 bolts (1 in the illustration).
6.5. Crankshaft pulley mounting bolts.
Installation is carried out in reverse order. Use new bolts (2 in illustration 6.1) and a new washer (3).
6. Bolts (10 in illustration 6.1) tighten the fastenings of the generator bracket (11) and the intermediate pulley in the sequence shown in the illustration.
6.6. Sequence of tightening bracket bolts.
7. When loosening/tightening the bolts securing the coolant pump pulley or power steering pump, hold the pulley from turning using tool No. 3212 (see illustration).
6.7. Removing the coolant pump pulley (power steering pump - similar).
